Academic writing conventions vary by discipline: citation style, evidence type, structure, and tone all change with the subject. An essay that would score well in one department can lose marks in another simply because it follows the wrong conventions.
The parts worth knowing:
Each discipline developed its own conventions because of the kind of evidence it values. The sciences put weight on recent research and data, so their citation styles foreground author and date. The humanities often analyse texts closely, so page numbers and detailed notes matter more. Law relies on cases and statutes, which need their own system.
The differences go well beyond the reference list. Psychology and nursing papers often follow set sections like introduction, method, results and discussion. Literature essays focus on interpretation and close reading. History essays lean on primary sources and context. Business papers use frameworks, and law essays apply legal rules to facts.
What counts as strong evidence changes too. Scientific writing values experimental results and statistics. History values documents and archival material. Literature values quotations, and philosophy values logic. Using the wrong kind of evidence can make a well-written argument look weak to a marker in that field.
Tone shifts with the subject as well. Some disciplines discourage the first person, while others allow it in reflective or method sections.
Style manuals and university library guides set out the formatting rules in detail. Reference managers such as Zotero, EndNote or Mendeley keep citations consistent. They also save time when the same source appears in papers for different courses.
Students taking courses in several departments often mix styles by accident. A short reference sheet for each course helps prevent that. And when the general advice and your instructor disagree, the instructor's requirements win.
The takeaway:
The parts worth knowing:
- APA - Psychology, nursing, business
- MLA - Literature and languages
- Chicago - History and philosophy
- Bluebook - Law, with OSCOLA abroad
- CSE or Vancouver - The sciences

The takeaway:
- Citation style is the first thing a marker notices.
- CollegeEssay.org has a detailed breakdown of how essay expectations change by subject, which is where most of this came from.
- Anyone want to add to this? Keen to hear what people found mattered most.
